So I'm trying to query data extension Data123, and I want to grab all rows where Email_Address doesn't contain 'TEST'. I thought the proper syntax would be Select * from Data123 Where Email_Address NOT LIKE '%TEST%'. However, when I input this, I get
" An expression of non-boolean type specified in a context where a condition is expected, near 'Name'."
Not sure what the correct syntax is here? Unfortunately, I do not understand the SFMC SQL documentation: https://help.salesforce.com/articleView?id=mc_as_using_the_query_activity.htm&type=5
